To @ZZ whomb it mag/concern: i

f `Be it known that LJOHN STARK, a citizen of the United States, and aresident kof Chester, in the county 'of'Delaware and State ofPennsylvania, have invented a` certain' new and usefullmprovement inHydrocarbon-Burners, of which improvement the following is aspecification.v f

My invention relates4 to means for utilizing hydrocarbon liquids aswfuelin furnaces of the various knownytypes, and its object vis to provide anappliance "of such character, inthe operation of which the constituentmolecules Yof steam may be. yaporized into their constituents ofhydrogen and oxygen,

and combined with vaporized molecule'sfof"l hydrocarbon liquid, and theresultant gas be projected into a furnace chamben-insuch manner as toeffectively `andeconomically exert and kmaintain a high degree of heatrtherein.

The improvement fully set forth:

In the accompanying drawings fFigure l, is a section, through a portionlof an end wall of a furnace, with the appliance of my invention shown inelevation; Fig. 2, a plan view ofthe appliance; Fig. 3, a side view,partly in section, of the same; Fig. 4, a transverse section, on theline 4 7-4 of Fig. 3; Fig. 5, a partial longitudinal section, on anenlarged scale, through the hydrocarbon tube,

claimed is `hereinafter Fig. 6, a partial axial section, illustrating an' structural modification of the appliance;

Fig. 7, a partial axial section, on an enlarged l scale, showing oneform of the ejection nozzle; Fig. 8, a transverse section through thesame; Fig. 9, a partial axial section, showing another form of ejectionnozzle; and,

Fig. 10, an end view of the same.

In the practice of my invention, referring descriptively to the specificembodiment thereof which is herein exemplified, and

premising that it is not limited in applica-v tion to any particularform of furnace or heating chamber, I provide an' inner hydrocarbontube, 1, leading from a source of supply of hydrocarbon liquid, and anencircling outer vaporizing tube,'2, each of which is connected, at oneend, to a block or Lcoupling member 3, which is supported, by a suitablelink or other connecting member, l, in proximity to an opening, 5a, of a`metallurgical furnace, 5. The hydrocarbon tube is closed at its endfarthestvfrom the coupling member, 3, and is open thereinto atitsfopposite tion with Aa .hydrocarbonsupply pipe, l.

end, at .which it .is in', continuous `communicaplurality of conicaloutwardly taperingde,

livery passages, 1 1?, shown vclearly `Ain Fig. 7, are formed `1n thehydrocarbon tube, 1, ex-v tending 4,for afportion ofits length from itsclosed "endtoward its oppositeend. Thehyv drocarbon tube is vmaintainedin Vconcentric,

relation to kthe vaporizing jtube, y2, an .interposed spacer'or spacers,l?. l

vAn .ejection nozzle, ld., the opening of `which is ,preferably oblong,or substantially quadrangularfin form, with its .longer koli-l..

mension locatedk horizontally, is `formed on,

7o or fixedjto-the hydrocarbon tube, at its vend n farthest .from thecouplin4 .memben `Fory applicationi-n open ,hearth urnaces, the verticalsection V,of .the ejection nozzle may {desirably l be .made .tapering`inwardly .toward the outlet, as'shown inl 1nig. 1,;and for .other work,as'hea'ting .ovens,;.coke ovens, anneal-v ingfpits,et`c.,`be'taperedoutwardly asshown inv Fig'. 9soasto produce ya wideriflama or cone thatisless concentrated.' f A steam supply pipe, 6leading from alsteam boiler (not shown) extends longitudinally,`adjacent to thevaporizing tube, 2,

`and toor near the ejection nozzle thereof,"y

and after being helically turned into a superheating coil, 6, isreturnedto a connection with the coupling member, 3, through a passage,6l, within which, itis continuously in open communication with thevaporizing tube, 2. Itfmay, however, if-preferred,

as shown in the structural modification, Fig. 6, be connected to thehydrocarbon .tube atk a point nearer thevejection nozzle thereof.k

The hydrocarbon' tube and the 'steam supply pipe `are independentlycontrolled by suitable regulating valves le and 6., respectively, and itis to 'be understood that the hydrocarbon tube is to be madeofmaterialsuf- ,v

melted or burned out within anunduly short vficiently refractory toprevent` it from being tube isto be extended into the furnace cham- Y fber forvsuch length, determined by operative conditions, as may befounddesirable for the? application of the necessary degree ofheat. In theoperation of the appliance, the high degree of heat imparted to thesteam, inits passage through the steam supply pipe and superheatingcoil, effectsthe vaporization of the steam into its constituent elementsofvhy drogen and oxygen, the heat of which, acting upon the outersurfaceof lthehydrocarbnn,`

and its combustion in the furnace chamber,

effects 'the'eXertion of a high degree of heat therein.

I claim as my invention and desire tosevcure by Letters Patent:

1 The combination of a block coupling member, provided With passage-Waysforhydrocarbon and superheated steam, a relatively long and unobstructedhydrocarbon tube connected to the hydrocarbon passageivay in said block,said tube being provided in its outer end portion with a plurality ofcircumferential delivery passages, an outer ifaporizing tube inclosingand spaced 'troni the hydrocarbon tube, said latter tube being connectedat its inner endto the superheated steam passage-Way of the blockcoupling member, and having its outer end terminating in an ejectornozzle, a steam` Supply pipe extending outsideof and in adirection inline with thevaporizing tube, a vsuperheater in the line of the steamsupply pipe comprising a coil formed about the outer end of thevaporizing tube adjacent the nozzle thereof and a valve controlled pipesection leading into the steam supply pipe and adapted for connection toa source of steam supply.

2. The combination of a block coupling` member, provided Withpassage-Ways for hydrocarbon and superheated steam, a relatively longand unobstructed hydrocarbon tube connected to the hydrocarbon passage-Way in said block, said tube being provided in its outer end portionwith a plurality of circumferential delivery passages, an outervaporizing tube inclosing and spaced from y the hydrocarbon tube, saidlattertube being supply pipe and adaptedk for connection to a source ofsteam supply. 1 p
